Probability of Coverage and Connectivity in Large-Scale Unreliable Sensor Network
نویسندگان
چکیده
We consider the coverage and connectivity problem of a sensor network with n unreliable nodes, uniformity arranged over a square region of unit area. We propose a novel triangle-arranged circle division method to obtain the the formula of the relationship of probability of coverage and connectivity, sensing radius, transmission radius, failure probability and the numbers of the nodes using probability method. Based on those,the design principle of sensing radius, transmission radius, failure probability and the numbers of the nodes for wireless sensor networks is given. We extend the ratio of transmission radius to sensing radius to arbitrary value and obtain good result.

Representing a Model for Improving Connectivity and Power Dissipation in Wireless Networks Using Mobile Sensors
Wireless sensor networks are often located in areas where access to them is difficult or dangerous. Today, in wireless sensor networks, cluster-based routing protocols by dividing sensor nodes into distinct clusters and selecting local head-clusters to combine and send information of each cluster to the base station and balanced energy consumption by network nodes, get the best performance ...

We consider an unreliable wireless sensor gridnetwork with n nodes placed in a square of unit area. We are interested in the coverage of the region and the connectivity of the network. We first show that the necessary and sufficient conditions for the random grid network to cover the unit square region as well as ensure that the active nodes are connected are of the form p(n)r(n) ∼ log(n) n , w...

Communication security of wireless sensor networks is achieved using cryptographic keys assigned to the nodes. Due to resource constraints in such networks, random key pre-distribution schemes are of high interest. Although in most of these schemes no location information is considered, there are scenarios that location information can be obtained by nodes after their deployment. In this paper,...
